Exhaust cutouts - recommended makes/suppliers?

[donkmeister]

I'm considering fitting electronic cut-outs to my family car. It's a quiet old V8 barge and I want to maintain that MOST of the time, but I like the idea of being able to run it with a proper V8 tone. Nothing ridiculous, I'd install them between the resonators and silencers rather than having some super loud silliness

Any recommendations for where to get these in the UK? I'm aware some are prone to seizing, rattling etc so looking for a recommendation. I'd most likely get a local exhaust place to fit them in, but may leave it to my next DIY day ramp hire and do it with band clamps.

Can’t help with a source but be mindful of where the hot exhaust gases go; just having them exit at some point along the way may warm something that is best not warmed.
